Rebel is 5 1/2 months old and just started barking during the night to go out. When he gets outside he just checks things out, doesn't even pee! This just started a couple of nights ago. We have noticed coyotes howling a lot more and close to us so that could be it. We leave a TV on and the other 2 dogs are in the same room as him. He is crated, they are not. The other 2 are not barking. We tried to ignore him but he will stop long enough for us to drift off to sleep and then start up again. I was wondering if it was time for the bark collar. FYI We have a wireless efence and started him on it last week with no problems.

Put one on mine at 4 months because of constant yapping while left alone.  7 days later no more yapping.  Her atitude has not changed

 i bought the TT Limiter and seems to be going well.
